I guess we'll also need the bindings generator in a hypothetical C++ SDK.

[vardhan, 2016/02/17 22:31:08]

do we need to include the mojo/public/third_party/jinja2 dependency, or can we
just assume the builder's system has that python library installed?

(broader question:  will this spec copy enough things to run the code generator
to completion on not-our-machines?)
